elevation training meaning in English

高低瞄准

In the study of directional spectrum and reflection coefficient of multidirectional wave , firstly the wave elevation trains overlapped by the incident wave and the reflected wave of multidirectional wave are simulated in the method of a frequency corresponding to a direction . then the composed wave trains are analyzed respectively by the mbdm and the mmlm . during the numerical study , the input factors include the various wave parameters , the different measuring wave system and the various reflect characteristic
在多向不规则波入射波方向谱和反射系数的分析研究中，利用方向频率对应法模拟了多向不规则波入射波与反射波叠加的波面序列，将此合成波列分别应用mbdm和mmlm进行分析，通过输入各种波浪参量、不同波浪测量系统和各种反射特性等因子，检验了mbdm和mmlm方法的适用条件，对两种分析方法的性能进行了比较分析。
